Forum: prelinger Subject: Re: What is the highest quality format?MPEG2?

MPEG-2 is the compression scheme and file format of DVD's, but not all MPEG-2 or DVD video is the same. The highest quality files of films here are the MPEG-2's, yes. And every film here that I have seen (about a thousand) was originally in 4x3 aspect ratio, but that doesn't mean the MPEG-2 version has a resolution that is of the same ratio - some are 480x480 (higher vertical than horizontal resolution - non-square pixels). The newest batch seem to be 640x480 (square pixels, and I like these cause my cheap video editing program knows how to handle them). Much commerical DVD video is 720x480 (higher horizontal than vertical resolution but still 4x3 aspect ratio). Video you would shoot in a DV camera would actually be higher quality - and tremendously larger file size.
